Patent CA-2475831-A1 (CA)
Inventor: STONES KEVIN
IPC: H01H9/06
Filed: 2004-07-28
Abstract: A drive mechanism for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing, and an output shaft adapted to be caused by the motor to execute reciprocating motion. The drive mechanism comprises a gear plate (34) adapted to rotate about a first axis (Z-Z) and having a plurality of elongate first teeth (33) extending substantially in a plane perpendicular to said first axis; and connecting means cooperating with said gear plate (34) and adapted to cause reciprocating movement of an output shaft of the tool in response to rotation of said gear plate about said first axis, wherein said reciprocating movement has a component perpendicular to said first axis. Conventional drive mechanisms which have an output shaft adapted to be caused by the motor to execute reciprocating motion generally have bevel gears with teeth formed at 45° to the axis of rotation of the gears. By providing a gear plate and connecting means which provide a reciprocating drive force for an output shaft of a power toot with teeth formed at 90° to the axis of rotation of the gear, instead of teeth formed at 45° to the axis of rotation of the gear, this provides the advantage that the gear is cheaper and easier to make as the gear teeth do not have to be formed as accurately as prior art inclined gear teeth. Also, the gear plate does not need to be as accurately located relative to the gear driving it, since some longitudinal movement in the direction of the mutually engaging teeth is possible without the gears ceasing to function correctly.

Abstract: Safety improvements of airport runways and taxiways are achieved by providing a flexible, water-impermeable surfacing material (14) on a compacted soil base directly adjacent to an edge of airstrip shoulders (12). A synthetic grass surface (30) is provided on the area beyond the surfacing material (14) so that foreign objects such as loose particles of the airstrip shoulder materials will be driven by jet blasts and run-off across the relatively smooth texture of the surfacing material (14) and will be trapped by the synthetic grass (30), thereby minimizing foreign object damage to aircraft engines, particularly to those overhanging engines which extend well beyond the existing runway and taxiway shoulders.

Abstract: A filter for filtering fluids is made by stacking two or more strips of flexible material and then wrapping the stack around a center line to form a spiral shaped roll that has several laps of said strips. The resulting roll has an input side which is the bottom wall of a reservoir which contains the fluid to be filtered such as the runoff water from a parking lot. The reservoir may have a by-pass outlet which by-passes the water around the filter in the event that the flow rate of the incoming runoff water exceeds the maximum rate of flow at which the filter is efficient. The strips guide the fluid as the fluid passes through the filter.

Title: Production of modified glycoproteins having multiple antennary structures
Inventor: GERNGROSS TILMAN U
IPC: C07K14/39
Filed: 2004-02-20
Abstract: The present invention relates to eukaryotic host cells, especially lower eukaryotic host cells, having modified oligosaccharides which may be modified further by heterologous expression of a set of glycosyltransferases, sugar and sugar nucleotide transporters to become host-strains for the production of mammalian, e.g., human therapeutic glycoproteins. The process provides an engineered host cell which can be used to express and target any desirable gene(s) involved in glycosylation. Host cells with modified lipid-linked oligosaccharides are created or selected. N-glycans made in the engineered host cells exhibit GnTIII, GnTIV, GnTV, GnT VI or GnTIX activity, which produce bisected and/or multiantennary N-glycan structures and may be modified further by heterologous expression of one or more enzymes, e.g., glycosyltransferases, sugar, sugar nucleotide transporters, to yield human-like glycoproteins. For the production of therapeutic proteins, this method may be adapted to engineer cell lines in which any desired glycosylation structure may be obtained.

Title: Electrical domain compensation of non-linear effects in an optical communications system
Inventor: O'SULLIVAN MAURICE S
IPC: H04B10/18
Filed: 2004-04-02
Abstract: Nonlinearity induced signal distortions are compensated by processing an input communications signal, in the electrical domain prior to Electrical-to-optical conversion and transmission through an optical link of a communications system. According to the invention, a compensation operator is determined that substantially mitigates the nonlinearity induced signal distortions imparted to an optical signal traversing the communications system. The input communications signal is then input to the compensation operator to generate a predistorted electrical signal. This predistorted electrical signal is then used to modulate an optical source to generate a corresponding predistorted optical signal for transmission through the optical communications system.  With this arrangement, arbitrary nonlinearity induced signal distortions imparted by the optical link can be compensated in such a manner that a comparatively undistorted optical signal is obtained at the receiving end of the optical link.
